This Aborvito Long Tube Headers set is designed for selected 1966-1987 Chevy and GMC C/K series trucks, Blazer, and Suburban applications with Small Block Chevy SBC V8 engine families, including 283, 305, 327, 350, and 400 engines. The header set features polished stainless steel construction, 1-1/2 in. primary tubes, 3 in. collectors, 5/16 in. head flanges, and 16-gauge tubing. It is intended for compatible classic Chevy and GMC truck exhaust systems where vehicle fitment, engine bay space, flange alignment, tube layout, and collector position need to be checked before installation.

Before installation, please confirm your exact vehicle year, model, trim, engine size, fuel type, drivetrain, steering clearance, motor mount setup, transmission area, spark plug style, plug wire routing, and exhaust connection layout. Fitment can vary on older Chevy and GMC trucks, especially with 4WD models, stock-height 4WD setups, different motor mount layouts, frame clearance, bolt-hole alignment, and front driveshaft clearance. Professional installation and test fitting are recommended before final tightening to help confirm proper positioning and surrounding clearance.
